Exhaust Valve/Flap Controller for Porsche

F1 Exhaust #1

Best sounding exhoust for the 991. 1 quite when you need it and loud when you want to feel it .

Not used.

I did not feel the need to use this presently, and was advised by your representative, that he could issue me a refund for part of the cost of this

Exhaust Valve Controller /22 Porsche 718 Spyder

I purchased a Valvetronics system (OAP and Exhaust) which came with the valve controller. Install was easy and works great bypassing the OEM Porsche valve open/close button. The OEM valve controller doesn’t open until your RPMs go above 4000 and this kit solves that issue. I’m enjoying it for sure
